| 1 | Is there a real diagnostic impact of elastosonography and contrast-enhanced ultrasonography in the management of thyroid nodules?显示文摘Ultrasonography(US) and the new applications US elastography(USE) and contrast-enhanced US(CEUS) are used in the screening of thyroid nodules,for which fine-needle aspiration biopsy(FNAB) is the best single diagnostic test.The aim of the study was to compare the sensitivity,specificity,positive predictive value(PPV),and accuracy of the four examinations in nodules with cytological and histological diagnoses.The study used data from US,FNAB,USE(elasticity(ELX 2/1) index),and CEUS(Peak index and time to peak(TTP) index) evaluated in 73 thyroid nodules in 63 consecutive patients likely to undergo surgery.Cytological-histological correlation was available for 38 nodules.No correlation emerged between nodule size and cytological results.A significant(P=0.03) positive correlation between cumulative US findings and cytological results was found.In addition,significant correlations between cumulative US findings and cytology(P=0.02) and between cumulative US findings and histology(P<0.0001) were found.US showed the best specificity and PPV,and FNAB the best sensitivity.There was no significant difference in the ELX 2/1 index,Peak index,or TTP index among nodules subdivided according to cytological scores.No significant correlation was found between ELX 2/1 index,Peak index,and TTP index,on the one hand,and nodule size,US cumulative findings,cytology,and histology on the other hand.The sensitivity of the ELX 2/1 index was high,but its specificity was very low.The accuracy and PPV of USE were lower than those of the other procedures.Only the correlation between Peak index and cumulative US findings reached a value close to significance.Our ultimate aim is to minimise unnecessary thyroidectomy.US and FNAB continue to play a central diagnostic role.The use of a US score showed high specificity and PPV.The specificity of FNAB was low in this selected series because of the numbers of indeterminate cytological responses.USE and CEUS are innovative techniques that need to be standardized.The ELX 2/1 index,Peak index,and TTP index seem to be unrelated to histology.The best statistical data on USE and CEUS concerned their sensitivity and PPV,respectively.At present,USE and CEUS are too time-consuming and of limited utility in selecting patients for surgery. | Massimo GIUSTI Davide ORLANDI Giulia MELLE Barbara MASSA Enzo SILVESTRI Francesco MINUTO Gianni TURTULICI | 2013 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2013，14，3： | 17 |

| 4 | 甲状腺不确定结节的回顾性细胞学评估研究(英文)显示文摘目的:回顾性分析了130例甲状腺不确定结节的临床评估和预后,以及组织细胞学检测结果,为甲状腺结节的治疗提供合理的治疗方法。方法:根据英国甲状腺协会2014年分类,回顾性分析了2011年1月至2014年12月130例甲状腺不确定结节(Thy 3)的细胞学检查。将结节分为Thy 3a(非典型特征)和Thy 3f(滤泡病变)两类。比较评估术前生物化学检查、彩色多普勒超声检查(US)、半定量弹性超声成像(USE)、超声造影(CEUS)、细胞学、组织学以及分子生物学突变分析等结果。结论:Thy 3结节的恶性肿瘤发生率较低,且在Thy 3a和Thy 3f之间没有显著差异。使用基于组织学的截取值作为参考可以降低采用手术的治疗方案。在阴性突变的Thy 3a和Thy 3f结节中,当不是所有的仪器检测结果都疑是阳性时,组织学观察应该作为首选。 | Massimo GIUSTI Barbara MASSA Margherita BALESTRA Paola CALAMARO Stefano GAY Simone SCHIAFFINO Giovanni TURTULICI Simonetta ZUPO Eleonora MONTI Gianluca ANSALDO | 2017 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2017，18，7： | 1 |
| 5 | Hepatitis E in hemodialysis and kidney transplant patients in south-east Italy显示文摘AIM:To investigate the serovirological prevalence and clinical features of hepatitis E virus(HEV) infection in end-stage renal failure patients and in the healthy population.METHODS:HEV infection is a viral disease that can cause sporadic and epidemic hepatitis.Previous studies unexpectedly showed a high prevalence of HEV antibodies in immunosuppressed subjects,including hemodialysis(HD)patients and patients who had undergone kidney transplant.A cohort/case-control study was carried out from January 2012 to August 2013 in two hospitals in southern Italy(Foggia and S.Giovanni Rotondo,Apulia).The seroprevalence of HEV was determined in 801 subjects;231 HD patients,120 renal transplant recipients,and450 health individuals.All HD patients and the recipients of renal transplants were attending the Departments of Nephrology and Dialysis at two hospitals located in Southern Italy,and were included progressively in this study.Serum samples were tested for HEV antibodies(Ig G/Ig M);in the case of positivity they were confirmed by a Western blot assay and were also tested for HEV-RNA,and the HEV genotypes were determined.RESULTS:A total of 30/801(3.7%)patients were positive for anti-HEV Ig(Ig G and/or Ig M)and by Western blot.The healthy population presented with a prevalence of 2.7%,HD patients had a prevalence of 6.0%,and transplant recipients had a prevalence of 3.3%.The overall combined HEV-positive prevalence in the two groups with chronic renal failure was 5.1%.The rates of exposure to HEV(positivity of HEV-Ig G/M in the early samples)were lower in the healthy controls,but the difference among the three groups was not statistically significant(P>0.05).Positivity for anti-HEV/Ig M was detected in 4/30(13.33%)anti-HEV Ig positive individuals,in 2/14 HD patients,in1/4 transplant individuals,and in 1/12 of the healthy population.The relative risk of being HEV-Ig M-positive was significantly higher among transplant recipients compared to the other two groups(OR=65.4,95%CI:7.2-592.7,P<0.001),but the subjects with HEV-Ig M positivity were numerically too few to calculate a significant difference.No patient presented with chronic hepatitis from HEV infection alone.CONCLUSION:This study indicated a higher,but not significant,circulation of HEV in hemodialysis patients vs the healthy population.Chronic hepatitis due to the HEV virus was not observed. | Gaetano Scotto Filippo Aucella Giuseppe Grandaliano Domenico Martinelli Mario Querques Antonio Gesuete Barbara Infante Paolo Delli Carri Salvatore Massa Giovanna Salatino Fabio Bulla Vincenzina Fazio | 2015 | World Journal of Gastroenterology2015，21，11： | 1 |
